Does it eventualy come right again?  Perhaps I should be more patient.
What I have seen is that all disk accesses appear to hang forever (but
maybe it's only "a long time", not "forever", see "be more patient"
above); the mouse pointer still moves in X, but trying to raise a window
that was not at the top fails, pressing enter in a shell that's already
running prints the prompt again, pressing alt-control-F<n> to switch
virtual consoles works when switching to a text console, but trying to
get back to the virtual console where X is running fails (I see a blank
text screen with a flashing hardware cursor), pressing the power button
for a short time doesn't do anything noticeable (it's supposed to make
powerd run a script that does an ACPI shutdown); I have to press the
power button for a long time to turn power off.

(I am running 4.99.49 now, but I have seen this behaviour for some time
-- OK in 4.88.38, I am not sure about 4.99.42, and bad in 4.99.48.)
